Network Rail said the level crossing in Oxfordshire, at which a man died today, was in full working order after a problem with the barrier was fixed at the site last year.
A spokeswoman said the barrier's slow rise and fall was corrected when a treadle, which operates the crossing when triggered by an approaching train, was replaced.
Speaking following reports of a long-standing fault at the crossing, she said:
The level crossing was in full working order before (today's collision between a car and a train). The lights were working and the barriers. That is part of the investigation so we will be looking at that. There is nothing to suggest it was not working beforehand.
